Luonnononnettomuuksien varoitusjärjestelmä (natural hazards early warning system) A closed system for official use Coordinated by the ministry of transport and communication 24/7 duty service Began operation in 2012 What is LUOVA?

Space weather monitoring was added to LUOVA in spring The routines and instructions for space weather monitoring were created by FMI space scientists. Education for LUOVA operators was arranged. Scientists support LUOVA operators mainly during office hours. We are planning to commence a regural on-call-duty cycle of space scientists from January Space weather in LUOVA

SW warnings are based on NOAA scales Currently we warn for: Geomagnetic storms G5 Solar radiation storm S5, S4 and S3 Radio blackouts R5 and R4. Expect <10 warnings per solar cycle in each category.

NOAA alerts interpreted automatically A script checks the NOAA warnings and alerts. Essential information is distilled for the LUOVA operator. If LUOVA threshold is exceeded, the script instructs the operator to issue a LUOVA warning. Magnetic activity in Finland Links to instructions Interpreted NOAA messages

At 2:28 Finland local time (0:28 UT) on 9 Jan, LUOVA warning for S3 solar radiation storm was issued. LUOVA duty person produced the warning using model texts. FMI scientists followed the event the next day, but space weather calmed down and no further warning was needed. Case: proton event on 9 Jan 2014

Monitoring currently based on NOAA alerts FMI has also own observations and tools for analysis during an event: Magnetometers, auroral cameras GIC models Magnetospheric simulations Nowcast model for low-energy electrons (talk by N. Ganushkina). Primarily research tools, these are now being developed for operational use. FMI space weather tools

Magnetic activity in Finland FMI operates a magnetometer network in Finland (part of IMAGE). A statistical model predicts the activity during the next hour from ACE solar wind.

Aurora nowcast Based on magnetic activity level Includes alert service wintertime

Substorm zoo: a dashboard and time series analysis tool also available to LUOVA operators

Challenges Meteorologists not able to interpret SW data On-call duty planned SW not relevant to all customers Only largest storms Need tailoring of alert distribution SW as a part of a wider hazard warning system Cost-effective 24/7 duty Use weather service’s operational experience Synergy in communication solutions Increases awareness Conclusions
